A massive search and rescue operation is underway off the coast of Argentina. Last Wednesday, the ARA San Juan, an Argentinian military submarine, went missing with 44 crewmembers on board. There’s a good chance the crew are still alive and trapped inside. Now the tricky part is finding them. Teams from Argentina, Brazil, the US, the UK and France, among others, have now united to find the submarine, but there isn’t much time left.
